This skill is purchased based on the source. So, a Dwarf would purchase Weapon Affinity III:Dwarf and it would apply to any weapon listed in the Dwarf affinity description, and a member of the military would purchase Weapon Affinity II:Military and it would apply to the weapon listed under Military affinity.

This skill allows the character to call three (3) additional points of damage when using a weapon which his / her race has a special affinity with, and they have skill in.

For example, if the and Eldarine purchased the Weapon Affinity I skill and knew One Handed Bladed weapons they would add three (3) additional point of damage when using a Rapier, thus calling 6 normal (3 base and +3 for this skill).

Furthermore, the Weapon Affinity always applies to both hands, thus right or left. Such that if an Eldarine has the skills to use two weapons, and is fighting with two Rapiers, and has Weapon Affinity I they would call 6 normal when striking with Rapiers in both hands (3 base and +3 for this skill).

Lastly when fighting in the races favored style, and coupled with that Races Weapon Master this skill offers a bonus of three (3) points of Physical (Melee) Damage Reduction

This skill unlike all the damage skills does not count for the prerequisites for the more advanced strikes attacks such as Critical Strikes and such.

This skill will stack with any other damage enhancing skill such as Weapon Damage and Enhanced Strength.

The damage bonus from affinities with different sources will not stack, such that an Eldarine member of the military could gain a bonus from Weapon Affinity III:Eldarine or Weapon Affinity II:Military for a +3 damage bonus when using a rapier.

The DR bonus for those that receive them also do not stack. Only the highest bonus will apply.
